Question: Is Vultr DDOS protection any good / worth the money? ($10/month)
We personally don't recommend Vultr's DDOS protection. In our opinion, it's not worth the money and it doesn't provide meaningful support. Even an incredibly small DDOS attack, by modern Internet standards, would completely overwhelm that level of protection.
Instead, we'd suggest using a service like Cloudflare, which has a completely free tier that includes DNS, WAF, CDN, and DDOS protection.
There are other good paid options like Stackpath. but Cloudflare is a great starting point, especially if you don't have very specific requirements.
